Made with

Pride and without

Compromise in the

All Guns are Not Created Equal.

A MIG gun should be durable, easy-

to-use and customized to your specific

application. Our MIG guns put you in

control: you choose the options you

need and we'll build a gun to last.

Centerfire

Contact Tips, Nozzles and Diffusers

are easy-to-use and high performing - they

provide better arc starts, less spatter and more

consistent welds - and also last up to three times

longer than competitive brands.

One piece HD straight handle with rubber

overmold is exceptionally durable and

comfortable in multiple hand positions.

Armor protected standard locking trigger can be

coupled with dual schedule switch, allowing guns

to be performance matched to user preference.

Necks available in fixed, rotatable and multiple

length options for optimal weld accessibility and

improved operator comfort. Rotatable necks

changeover without tools.

Jump Liner allows quick neck change and

replacement of only most commonly worn or

clogged liner area, which reduces the amount of

time a gun is offline and minimizes inventory.

Back end with durable rigid strain relief and

easily interchangeable direct plugs and trigger

leads connect to wire feeders and machines

from major manufacturers and allow simple

maintenance.
